96 Points - Vinous:  The 2021 Cabernet Sauvignon Howell Mountain is another impressive wine from O'Shaughnessy Estate Winery. Bright acids and beams of tannin run through a core of dark red/purplish Howell Mountain fruit. Potent yet refined, the 2021 is a fine effort. Blueberry jam, plum, lavender, chocolate and graphite all build into the huge, vibrant finish.
